Integumentary System

The Integumentary SystemThe Integumentary System, consisting of the skin, hair and nails, act as a barrier to protect the body from the outside world. It also has several other functions in the body. The word INTEGUMENT comes from a Latin word that means to cover. The most important function of the integumentary system is protection. This system 1) serves as a barrier against infection and injury, 2) helps to regulate and maintain body temperature, 3) removes waste products from the body, 4) provides protection against the sun's ultraviolet radiation, and 5) produces vitamin D for the body.

The skin is a protective covering, also the largest organ in our body. It is composed of an epidermis and a dermis separated by a basement membrane. A subcutaneous layer, not part of the skin, lies beneath the dermis. The skin houses several different types of glands such as sweat glands, sebaceous glands, and apocrine glands.

Nails are protective covers on the ends of fingers and toes. They are produced by epidermal cells that undergo keratinization. Hair occurs in nearly all regions of the skin. Each hair develops from epidermal cells at the base of a tube like hair follicle. As newly formed cells develop and grow, older cells are pushed toward the surface to undergo keratinization. A bundle of smooth muscle cells and one or more sebaceous glands are attached to each hair

As stated, the integumentary system serves several different purposes in our body. It is a very vital system and it is needed for protection and stabilization inside and outside of the human body.

...The IntegumentarySystem
I. Introduction
My chosen organ system is the integumentarysystem.
II. The Integumentary System’s function is to protect and support organs in the body hence this is why its largest organ is the Skin.
a. The skin protects underlying tissue against harmful bacteria, it provides barriers against most chemicals, it also reduces the chance of injury due to mechanic equipment
b. The skin also helps regulate body temperature.
c. It regulates the body temperature by thermo regulation and sweating.
III. The Integumentary system’s main contribution to homeostasis is the ability to regulate body temperature.
IV. The skin consists of the epidermis, dermis and the hypodermis.
a. The epidermis is the outer layer.
b. The dermis is the middle/second layer.
c. The hypodermis is the layer (fatty) just under the skin
The integumentarysystem also consists of epithelial membranes, accessory structures of the skin.
Chemistry is important to the healing of burns and the forming of melanin and melanocytes.
V. V. The integumentarysystem has the three epithelial membranes which are cutaneous, serous and mucous, which directly support the organs.
a. Cutaneous membranes-this is the skin
b. Serous membranes-lines body cavities.
c. Mucous membranes-lines body surfaces

...The topic of section sixteen is the pathophysiological changes that can occur in the integumentarysystem. These include inflammatory reaction of the skin and the formation of lesions, burns, cellulitis, dermatitis, folliculitis, furuncles, carbuncles, fungal infections, pressure ulcers, psoriasis, scleroderma, toxic epidermal necrolysis and warts. All these possible alterations mentioned applies to physiology because the integumentarysystem, which consists of the skin, the subcutaneous tissue below the skin, hair, nails and assorted glands protect our body from invading microbes (chemically and physically), regulates body temperature, prevents dehydration, acts as a blood reservoir, aids in excretion and vitamin D synthesis.
The skin is the largest and heaviest body system, and it takes a lot of work to keep it balanced. It is considered one of the most valuable parts of the body. Since the skin is our first line of defense, we must take necessary precautions to keep it healthy and prevent any kind of infection from developing and spreading. The hair and nails both have protective functions in addition to their cosmetic appeal. The integumentarysystem has two main types of glands, sebaceous (oil) and sudoriferous (sweat). The sweat glands function primarily in thermoregulation by the production of sweat, and sebaceous glands produce oil that keeps the skin and...

...﻿Skeletal, Muscular, and IntegumentarySystem
The Muscular System
Our muscular system provides the main source of force to put our bodies into motion.
More than 40% of our body mass is composed of muscle.
Types of Muscular Tissue
There are three types of muscle tissue:
1. Skeletal
Voluntary movement, attached to bones.
2. Smooth
Involuntary movement, found in digestive tract,
circulatory system, etc.
3. Cardiac
Involuntary movement, found only in heart.
Muscle Contraction
Skeletal Muscle Muscle fibers Myofibrils Filaments
Two types of filaments:
- Thick: contain protein called myosin
- Thin: contain protein called actin
The alternation of myosin and actin form structures called striations.
The energy for muscle contraction is supplied by ATP.
Controlling Muscle
Contraction
Our muscle contractions are controlled by our nervous system.
The nerve impulses in our brain signal and regulate the contraction.
The neuromuscular junction is the point that the skeletal muscle and neurons come in contact.
How Muscles &
Bones Interact
The muscles and bones in our body are joined by a tough connective tissue called tendons.
As you move your bones, your muscles follow along.
Skeletal muscles work in opposing pairs: when one contracts, the other one relaxes.
Skeletal muscles generally remain in state of partial contraction (even when your legs are straight).

Skin sebaceous Glands are classified under the pilosebaceous unit and contain both a hair follicle and a hair. The glands are located everywhere in the body expect in the palms, soles, top of the feet, and the lower lip. The glands are heavily located on the face, upper neck and the chest. The glands produce sebum which is responsible for keeping the skin moisturized. The major function of the sebaceous glands is secretion of the sebum by a holocrine process. The sebum secreted is composed of triglycerides, wax esters and squalence. Sebum on the skin plays a crucial role in maintain a skin barrier by expressing pro inflammatory and anti inflammatory properties. Combination of sebum and other apocrine secretions have a thermoregulatory role (Smith, 2011).
Sweat glands are tube like structures located within the skin, in which sweat is produced and then transported to the surface of the skin. The sweat glands are classified into Eccrine and apocrine sweat gland. Every sweat gland contains a hollow tube, which is long and coiled like a ball at its base. The coiled part is usually located in the dermis. The duct allows sweat to move from the base towards the surface of the skin. The duct has a pore on the skin...

...Skeletal System
Skeletal system is the biological system providing support in living organisms.
Skin, muscle and bones allow movement. Skin - pliable covering. Muscles do actual moving. Bones give anchor to move against.
The skeleton functions not only as the support for the body but also in haematopoiesis, the manufacture of blood cells that takes place in bone marrow. This is why people who have cancer of the bone marrow almost always die. It is also necessary for protection of vital organs and is needed by the muscles for movement.
The human skeleton consists of both fused and individual bones supported and supplemented by ligaments, tendons, muscles and cartilage. It serves as a scaffold which supports organs, anchors muscles, and protects organs such as the brain, lungs and heart.
The biggest bone in the body is the femur in the thigh and the smallest is the stapes bone in the middle ear. In an adult, the skeleton comprises around 30–40% of the total body weight,[1] and half of this weight is water.
Fused bones include those of the pelvis and the cranium. Not all bones are interconnected directly: there are three bones in each middle ear called the ossicles that articulate only with each other. The hyoid bone, which is located in the neck and serves as the point of attachment for the tongue, does not articulate with any other bones in the body, being supported by muscles and ligaments.
